SAN
* Zoning
- Soft zoning restricts only the fabric name service, to show only an allowed subset of devices. Therefore, when a server looks at the content of the fabric, it will only see the devices it is allowed to see.
- Hard zoning restricts actual communication across a fabric. This requires efficient hardware implementation (frame filtering) in the fabric switches, but is much more secure.
- Port zoning restricts specific switch ports from seeing unauthorized ports.
- WWN zoning (also called name zoning) restricts access by a device's World Wide Name (WWN)
* LUN masking
- Authorization process that makes a Logical Unit Number available to some hosts and unavailable to other hosts.
* Components
- Storage processors – control access to SAN disks
- Ports
- Front-end – connect to HBA
- Back-end – connect to storage array
